Two general types of structures are these points the trolley rises to a normalheight of 22 ft. above the rail. At each signal bridge on the viaduct,circuits have been run between the sig-nals and relay boxes which are on top ofthe concrete piers and against the steelgirders. Access has been provided to the.

For the purpose of railroad communi-cation, a telephone and telegraph conduitline has been built connecting with thePennsylvania Railroad at SunnysideYard, and the New Haven Railroad atEast 132d St. between Harlem River andPort Morris, with connections into therailroad towers and to numerous tele-phones on the railroad. In the steel splicing chambers on theviaduct the telephone cable has been off-set to allow for expansion and contrac-tion of the steel girder, which amountsto about three-quarters of an inch. nHell Gate and Little Hell Gate Bridges,however, the maximum expansion in thebridge system will be about 111 ins. andhere the cable has been terminated withpotheads and llexihle rubber insulatedcables used for connection between thepotheads. South of Sunnyside Junctiona similar cable has been run along thefreight line to Bay Ridge. Length of
